Illicit Discharge Information
An illicit discharge is defined as any release into the drainage system (MS4) of contaminated water, or any non-stormwater discharge that contributes pollutants to receiving waters.
Public Works conducts inspections of stormwater outfalls throughout Town as part of ongoing compliance with our Phase II permit. Article XXXI - Illicit Discharge By-law (PDF) provides enforcement and fining procedures for illicit discharges found within the Town’s MS4. Any discharge deemed a threat to public safety, public health, or the environment is in violation of this by-law and thus subject to a removal order and / or fines by the Department of Public Works, Conservation Commission, Board of Health, or Inspectional Services.
